HOPPER.

Specification of Letters Patent.

Patented Mar. 9, i915.

To all whom it may concern Be it known that 1, ARTHUR R. Havanna, a citizen of the United States, residing at Waltham, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Hoppers, of which the following is a specification.

This Yinvention relates to a hopper for separating articles having a recess in one face thereof from a mass of the `same and feeding them one by one to a raceway or chute. The hopper is particularly adapted for separating and feeding rivet caps which have a recess in one face thereof and a projection within said recess.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a plan view of my improved hopper with the cover removed. Fig. 2 is a sectional elevation taken on line 2-2 of Fig. 1, with the coverin position. Fig. 3 is a sectional elevation taken on line 3-'3 of Fig. 1. Fig. 4 is a detail sectional elevation taken on line 4--4 of Fig. 2. Fig. 5 is a detail plan of the remover plate. Fig. 6 is a sectional elevation enlarged of a rivet cap.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 10 is the casing of the hopper and 11 the cover. The casing 10 has a bracketj12 thereon by means of which it is fastened to the frame 13 of the machine in connection with which the hopper is to be used. A picker plate 14 is rotatably mounted in the casing 10 and is rotated by means of a shaft 15 fastened thereto by a pin 16 and journaled to rotate in a bearing 17 in the casing' 10. rotary motion is imparted to the picker plate by suitable mechanism connected to the shaft 15 by a universal joint 18 which is rotated by means of a shaft 19 journaled to rotate in a bearing 2O in the frame 13. The upper face 21 of the picker plate 14 is inclined and an annular flange 22 is provided on the upper face of said picker plate adjacent to the periphery thereof, the upper face 23 of said flange being inclined toward the upper face 21 of said picker plate.

A series of projections 24, preferably in the form o f pins. are provided upon the pickerplate 14 and each of these projections is so formed as to be adapted to project into a recess .25 in the rivet cap 26 between the edge 27 and the center of said cap and at one side only of said center. The projections or pins 24 are of less diameter where they project into said recess than one-half the width of said recess and said projections extend beyond the face 21 of the picker plate 14 to such an extent that the rivet cap will be tipped at an angle to the inclined face 21 of the picker plate when said rivet cap is engaged by one of said pins, la's illustrated in 1 ig. 2.

The rivet caps 26 are each provided with a prjection 28 in the center thereof which is located in the recess 25 and projects from the base ofv the rivet cap into said recess. The pins 24 extend into the recess 25 between the edge 27 and the projection 28 and hold the rivet cap suspended at an angle to the face 2l of the picker plate 14, as illustrated in Fig. 2.

A stationary defiector 29 is fastened to the Wall 30 of the casing 10, the lower'edge 31l of said deflector plate lying adjacent'to the upper face of the picker plate 14, while the upper edge 32 of said deflector plate is inclined downwardly toward said upper face of the picker plate in a direction opposed to that in which that portion of said picker plate adjacent thereto is arranged to move,

whereby any of the caps 26 into which said pins do not project will be deflected toward the lower end of said picker plate. The rivet caps pass out of the hopper onto a raceway 33 which rojects into the interior of said hopper and) to the inclined face 21 of the picker plate 14.

The portion of the raceway whlch projects into the hopper consists of a cover l34 and a base 35 which performs the function of removing the rivet caps from the pins in Athe picker plate. The cover 34 is slotted at 36 and its inner end lies in advance of the inner end of the remover plate 35. Said base has a slot 37 at one side thereof throu h which the rivet caps can pass back into t e hopper when the raceway is filled up to said slot 37 with rivet caps. The upper end of the remover plate 35 isalso slotted at 38 to allow the pins 24 to pass alon beneath said remover plate and while sai pins are so passing beneath said remover piatte the is inclined at an angle Q meoeee ezio-s 39 project beneath the rivet cojo on cpposite' sides of the pin @eend iit said rivet cap olii of said pin, allowing the same then to siide ciown the base 55 beneath 'the cover 34 onto the iracewey 38.

The generai operation of the device hereinbefoie speciceiiy described is es oiioijvs: Rivet caps iii mass are placed iii the casing l of the hopper until said casing is pertiy lied, the rivet caps ceiiig iccetefi iii mess at the iowei' end of seid hopper. The picker piete is ioteted by any sui'tooie meciis through the medium o the shaft i9, imi- `versci ioiiit 18 end shaft l5 and es 'the picker piete passes eroim through the iowei end of the casing the pins pick up the rivet caps, eecii 'pin pojectiiig into the recess iii the iivet ccp between the edge 27 eiic the orog'ectioo 28. Said iivet caps are then ceiiieci around as iliusti'ated iii Fig, i hanging by iieii opper edges on the ends ci? the pins 2 emi with their lower edges :resting against the inclined iece :2i of the picker piate lei es iiiiistiated in ig, 2.
